Five Muslims apparently from the Washington DC area have been arrested in Pakistan: Breaking News: Pakistan Reportedly Detains Five D.C.-Area Muslims on Suspicion of Terror.

A Pakistani newspaper reports the arrest of five foreign nationals after a raid in a town called Sargodha. The raid took place at the home of a member of the Jaish-e-Muhammad, a Pakistani movement designated as a terrorist group by the U.S. Treasury Department in 2001.

According to the report, “The DPO told that these people had been living in Sargodha since Nov 30 and it was quite a possibility that they were engaged in acts of terrorism.” It names the five as Ahmed Abdullah, Waqar Hassan Khan, Eman Hassan, Yasir and Rami Zamzam and describes them as two Yemenis, an Egyptian, a Swede and a U.S.-born Pakistani.

The identities of two of the missing men, Howard student Ramy Zamzam and Waqar Khan, have been mentioned in online postings, including a Facebook page that was set up Monday for friends to offer their support. Some of those pages, however, appear restricted to friends and associates.

It is not clear where the men are believed to have gone, but an informed source told the IPT that at least one left behind a farewell video.

According to the Facebook and Twitter postings, Zamzam is among the missing. He has been active in the Muslim Students Association, serving as president of the MSA DC Council. A Howard University spokeswoman has not responded to questions from the IPT.

The disappearance comes as U.S. officials are increasingly concerned about the threat of homegrown Islamist extremism. This concern is prompted by a spike in attacks like the Fort Hood massacre, and conspiracies broken up by law enforcement before any attacks took place.
